I'm trying to figure out how SFML's CMake configuration shows the <SFML/*> include directory in a project folder.
My test project has include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include) but the include folder does not appear in the project structure like SFML's
The folder will show up if you have added any source files from within that directory (or a subdirectory below it) to any target in the project. Since you are talking about headers, you can simply add the header files as sources to an existing target. CMake will just ignore them as far as the building of that target is concerned, but it will then add those headers to the project's list of files. I've also seen people add a static library target with nothing but headers listed just so those headers show up in the project view. A bit hacky in my opinion, but it gets the job done.

I've been using CLion for a little while now, and I quite like it, except that it stores it's prject files by default in my CMake project. I am wondering if I can set a default place it stores it's project files(like compiled executables) in specific directory, per project.(So not one big folder that might interfere with other projects). The reason I want to do that is because I don't like having it in my git project(yes, I know about .gitignore) Anyone know how to do that?
Thanks!
To use a different folder for CLion building
In the CLion menu:
Build,Execution,Deployment -> Cmake -> Generation Path
Change the value to the folder path you want.
To include source code from a different folder out of current
In your CMakeLists.txt, add subdirectory like following:
add_subdirectory(<PATH_OF_YOUR_ANOTHER_CMAKE_PROJECT>)
Be aware PATH_OF_YOUR_ANOTHER_CMAKE_PROJECT can be anywhere on your computer, which does not have to be in your current project folder or one of the sub-folders.
I'm in the process of converting a rather huge project to a Windows 10 Store app. I've gotten it to compile and now can't get past several APPX1101 errors - "Payload contains two or more files with the same destination path". The files are .xml files part of the project, e.g. "baseDir\Assets\foo\timers.xml" and "baseDir\Assets\bar\timers.xml". Different files and different paths.
The solution and projects are created by CMake (3.72). The cmake files have been modified to support creating a Windows 10 store app platform config.
It appears that the directory tree has been flattened and files are overlapping. But how or why eludes me. Every UWP project I've seen contains an "Assets" folder under the main project but this one does not. I see files such as Logo.png and SplashScreen.png in folder named "Resource Files". The files causing the errors are under the folder named "Assets" which existed before this was a UWP project.
Primarily:
How can I fix this error? Did I misconfigure CMake?
Additionally:
How to avoid directory flattening?
There are a few hundred data files taking up a few hundred megabytes used by the program. Will I need to add each of them to the solution to be packaged?
Updates:
I've gleaned more info but not enough to fully satisfy the question. The directory flattening in the output occurs due to how the files are added to the project via CMake and how the original Windows product was packaged. The XML files are added to the project with a full path in the .vcxproj. The .vcxproj.filters also use a full path to the file and a filter like "Data\foo". The desktop Windows version didn't need to care since it knew where to find it's data relative to the executable and was packaged by an external tool.
I've manually added an "Assets" filter and modified the .vcxproj and .vcxproj.filters files. The .vcxproj file needed a property added to the file's include. This uses relative paths and gets rid of the APPX1101 duplicate error.
.vcxproj
<XML Include="..\Base\Assets\foo\Data\timers.xml">
<Link>Assets\foo\Data\timers.xml</Link>
</XML>
.vcxproj.filters
<XML Include="..\Base\Assets\foo\Data\timers.xml">
<Filter>Assets\foo</Filter>
</XML>
Update 2
From what I can tell, it's not possible to get CMake to add a <Link> to XML and other .vcxproj Include types. I went through the latest CMake source code (3.8rc). The <XML Include> is added to the .vcxproj in cmVisualStudio10TargetGenerator::WriteExtraSource() in cmVisualStudio10TargetGenerator.cxx. Other types have the option to set the flag to add the <Link> but XML and other data types do not have code to set the flag.
The only options I can see are modifying CMake source or reworking the project to add data files using relative paths that match the same <Filter> for the matching Include in the vcxproj.filters file. This is only a problem with CMake. Visual Studio 2015/2017 have no problem adding assets above your tree. The MS UWP examples on GitHub do it to share common data between sample projects.
It's been a while and I'm posting this as an answer in case someone else runs into this problem. I'm not marking it accepted because I find the workaround rather weak. My knowledge of CMake is limited and my understanding of Universal Windows apps even less.
The primary issue is that by design, CMake does not build a relocatable solution. i.e. you can't xcopy a Windows solution to another tree and expect it to work as you would would with one generated from within the Visual Studio IDE.
The second issue is that this was a huge pre-existing project already targeting multiple platforms. And by huge, I mean it ships on a dual layer blu-ray disc. The location of asset files was fixed and was above the location of the CMake build folder. This caused files to be stripped of their path when added to the layout whenever their location was not under the expected assets folder.
There is no way in the current CMake (3.8) to add a <link> tag to the include in the project file. And CMake creates the include tag with the full path to the file not a relative one by design.
The workaround I came up with was to add a step to the batch file that invokes CMake to edit the .vcproj and vcproj.filters files to change the fixed asset paths relative ones and then added another step to create a symbolic link/junction (SysInternals.com) under the build folder to the location where the assets were. The assets now appear as being under the expected asset folder are now added correctly to the layout.
As I said, not ideal but it works. The real solution would be to re-organize all the data but this is not something that can happen for this project when a vast amount of data is generated from different script, tools, sources and contributors.
First of all, I would like to make it clear that I know that the src folder is not required. Indeed, one can simply create manually one directory for the project, make one valid project.json and one Startup class and everything should work fine even without Visual Studio.
My point is the following: when we create a new project using ASP.NET 5 from Visual Studio 2015 it creates a solution and inside the solution's folder it creates one src folder. Within this folder all projects are created.
Now why would anyone want to make one src folder inside the solution folder? Why not putting the projects direct onto the solution folder? Is there any advange on the organization of the project to put the projects inside a src folder? Why VS does that now?
You usually have more files inside your project that are not source code related like:
README.md
CONTRIBUTING.md
.gitignore
LICENSE
Build scripts
Docs and tools folders, etc.
And a tons of others files that depend on your configuration. So, if you have a src folder, you don't need to mix your source code files with those.
because you may have your code in src folder (class libraries, etc), test in your test folder, documentation in a documetation folder
in global.json you specify which folders does roslyn pick for compiling.
I want to use FindAntTweakBar.cmake that it becomes able to find the anttweakbar, but I dont have administration access to the cmake's modules folder, so I cannot copy it there. Is there any way to include it and not copy it in the Modules folder? I am using the cmake-gui in the windows.
You can add it to a folder of your choice within your project instead, and modify the CMAKE_MODULES_PATH for that specific project in your CMakeLists.txt.
For instance, if you were to put it into a folder "[location of top-level CMakeLists.txt]/cmake", you would issue:
set(CMAKE_MODULE_PATH "${CMAKE_MODULE_PATH};${CMAKE_SOURCE_DIR}/cmake")
I have created a sample application to perform bump distortion, using the GPUImage framework. I added this framework to my application, but I'm seeing the following error
Lexical or preprocessor issue 'GPUImage.h' file not found.
I have added the -ObjC flag to the Other Linker Flags, but I'm still seeing this error. How can I solve this problem and get my application to compile?
Adding GPUImage framework to XCode project could be tricky. So I haved added detailed step-by-step instructions w/ images on how to do it.
Static Compilation Method (detailed solution so we don't mess up)
This is Static compilation method. In this basically we will compile the framework using ./build.sh file. And simply add it to our XCode project, then configure XCode to properly use it.
Download GPUImage from Github and extract it (or just clone it).
Go to the GPUImagefolder in terminal
Run ./build.sh
Note: This will compile and create ready-to-use binary for all the sdks on your mac.
build.sh creates a folder called build and generates compiled binaries and dumps them to folders like: Release-iPhone, Release-iPhoneOS, Release-iphonesimulator etc folders.
For iPhone use Release-iphone (This also works for simulator).
Copy (not drag-drop) Release-iphone to your XCode project's root directory so that we have a local copy of framework.
Now iPhone drag-and-drop Release-iphone onto your XCode project. Make sure to check "Copy to .." option.
Note:
This Release-iphone folder contains two sub-folders: include and lib
include folder contains all the header .h files
lib folder contains compiled binary version file called libGPUImage.a
We now need to simply configure XCode to use .h and .a files.**
Select your project in the project explorer > Project name under Targets > select Build Phases > Expand Link Binary With Libraries
Add the libGPUImage.a to Link Binary With Libraries section. You may want to Right-click on libGPUImage.a then Open in Finder and finally drag-drop it.
While we are at it, also add the following GPUImage's dependent frameworks/ libraries
CoreMedia, CoreVideo, OpenGLES, AVFoundation, QuartzCore to Link Binary With Libraries section
Now, lets configure .h headers.
Select your project in the project explorer > Project name under Targets > select Build Settings > and type search paths to see search paths section.
Open Headers Search Paths by clicking on the value field.
Drag-and-drop the lib folder to that popup. Note: If it shows absolute path, change it to looks $(SRCROOT)/path/to/lib/. (You should have the framework relative to your xcode project see step 6).
Repeat 11 & 12 for Library Search Paths as well.
Additional tips: You can add .h files to Library Search Paths or Headers Search Paths, you can make them Recursive. I have a main root-folder called Dependencies folder where I keep all the dependencies like MySDK-framework including Release-iPhone. And I just have one search-path at the Dependencies (root folder) and made it recursive.
Did you follow all of the instructions from the Readme on the project page? From the installation instructions:
You'll also need to find the framework headers, so within your
project's build settings set the Header Search Paths to the relative
path from your application to the framework/ subdirectory within the
GPUImage source directory. Make this header search path recursive.
If you're seeing the above error, it means that you did not point the Header Search Paths at the right directory where you've installed GPUImage relative to your project, and / or did not click the checkbox to the left to make those search paths recursive.
I show some screenshots of where you need to go to set this in this answer, which explains something similar for the Core Plot framework. The same principles apply, only you need to find where you installed the GPUImage framework at.
I add relative path to "Header Search Paths", but there is still a error that is "not found".
Then, I add path to "User Header Search Paths", and it works.
May help you.
finally, I realized the KEY WORD is relativeļ¼
I put GPUImage source files in my project root dir:
before I solved the problem, I add Header Search Paths is:
$(PROJECT_DIR)/GPUImage/framework
$(PROJECT_DIR)/GPUImage/framework/iOS
and make them Recursive, but error is still there, So I changed Paths to:
GPUImage/framework and make it Recursive, then it works.
Hope it helps.
