I am using Qt Creator as IDE and MSVC 2019.
I built and installed the pagmo library from the source. Now I am trying to use it for my project.
Even though the installation seems fine, when I try to load it I get strange errors, telling me that "pagmo" is not found. In particular:
error:
By not providing "FindPagmo.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Pagmo",
but CMake did not find one.
Could not find a package configuration file provided by "Pagmo" with any
of the following names:
PagmoConfig.cmake
pagmo-config.cmake
Add the installation prefix of "Pagmo" to CMAKE_PREFIX_PATH or set
"Pagmo_DIR" to a directory containing one of the above files. If
"Pagmo" provides a separate development package or SDK, be sure it has
been installed.
In my CMakeLists.txt I have set the following command:
find_package(Pagmo REQUIRED)
Now, as far as I know FindPagmo.cmake does not exist, BUT I am giving as input parameter Pagmo_DIR, which contains the file pagmo-config.cmake. I can't understand why CMake is not finding it. I also tried to set CMAKE_MODULE_PATH to the same folder but nothing changed.
Does anybody have suggestions on how to solve this problem?
I am setting pagmo directory as follows:
-DPagmo_DIR = C:\Lib\pagmo\install\debug\lib\cmake\pagmo
in that folder I have the following files:
Findpagmo_IPOPT.cmake;
pagmo_export.cmake;
pagmo_export-debug.cmake;
pagmo-config.cmake;
pagmo-config-version.cmake;
PagmoFindBoost.cmake

I am trying to simply open Qt6.4.1 sensors example project, but it says that no CMake configuration found. I already made some simple Qt6 applications for Windows, and i have entire Qt6.4.1 package installed, so cant blame on bad installation. There is an error on line find_package(Qt6 REQUIRED COMPONENTS Core Gui Quick Sensors Svg) in CMakeLists.txt. Full error message:
C:\Qt\Examples\Qt-6.4.1\sensors\sensorsshowcase\CMakeLists.txt:12: error: By not providing "FindQt6.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Qt6", but CMake did not find one. Could not find a package configuration file provided by "Qt6" with any of the following names: Qt6Config.cmake qt6-config.cmake Add the installation prefix of "Qt6" to CMAKE_PREFIX_PATH or set "Qt6_DIR" to a directory containing one of the above files. If "Qt6" provides a separate development package or SDK, be sure it has been installed.
Pass the path to the directory containing the Qt6 files via CMAKE_PREFIX_PATH cache variable during configuration.
Note: Make sure to specify the type of the variable as PATH or use forward slashes as path separator for this to work properly.
E.g. for me I'd need to pass
-D CMAKE_PREFIX_PATH=D:/Qt/6.4.1/msvc2019_64
to tell CMake to look into the directory containing the Qt6.4.1 files compiled with MSVC.
Make sure that the directory you pass contains the file lib/cmake/Qt6/Qt6Config.cmake; this is the file find_package(Qt6 REQUIRED COMPONENTS ...) is looking for.
You can also fix your project setup that previously failed by adding the cache variable.
cmake -D CMAKE_PREFIX_PATH=D:/Qt/6.4.1/msvc2019_64 path/to/build_dir
Note: Don't forget to add the -A ... option when configuring a VS project; CMake defaults to Win32 as architecture, at least on my system.
You could add this info to a CMAKE_PREFIX_PATH environment variable, if you don't want to specify the info cache variable for every single project using qt 6 that you want to set up on your machine.
By not providing "FindSW.cmake" in CMAKE_MODULE_PATH this project has asked
CMake to find a package configuration file provided by "SW", but CMake did
not find one.
Could not find a package configuration file provided by "SW" with any of
the following names:
SWConfig.cmake
sw-config.cmake
Add the installation prefix of "SW" to CMAKE_PREFIX_PATH or set "SW_DIR" to
a directory containing one of the above files. If "SW" provides a separate
development package or SDK, be sure it has been installed.
What I am trying to build is leptonica, but I can't do it without having there .cmake files, and I have no idea how I can get them, since I couldn't build SW.
I am trying to add aws-sdk-cpp as a submodule in my Qt application using Qt Creator and CMake. I want it to build for any platform without doing the building and installing on the command line as described here.
My project structure and CMakeLists.txt files looks like this:
I have successfully built the entire aws-sdk-cpp using MSVC2019 in debug mode using Qt Creator. My projects build folder is now 15 GB containing all the built libraries. The current issue I'm now facing is this error:
CMake Error at app/CMakeLists.txt:23 (find_package):
By not providing "FindAWSSDK.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "AWSSDK", but
CMake did not find one.
Could not find a package configuration file provided by "AWSSDK" with any
of the following names:
AWSSDKConfig.cmake
awssdk-config.cmake
Add the installation prefix of "AWSSDK" to CMAKE_PREFIX_PATH or set
"AWSSDK_DIR" to a directory containing one of the above files. If "AWSSDK"
provides a separate development package or SDK, be sure it has been
installed.
I think what is missing is the make install step described here and to set the path to AWSSDK_DIR.
I'm very new to CMake and I have not found any way to perform the make install step in the CMakeLists.txt file and then be able to set the AWSSDK_DIR which points to the AWSSDKConfig.cmake or awssdk-config.cmake file missing.
I'm also not sure which CMakeLists.txt file this should be written or if there is an entire other way to do this? Currently I'm stuck getting nowhere..
I'm trying to compile a program in CMake but I'm getting this error.
By not providing "FindVTK.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "VTK", but
CMake did not find one.
Could not find a package configuration file provided by "VTK" (requested
version 6.1) with any of the following names:
VTKConfig.cmake
vtk-config.cmake
I can't find the relevant files (VTKConfig.cmake or vtk-config.cmake) on the machine but do have VTKConfig.cmake.in (which also doesn't work).
Does anyone know where I can download the file from, or what I might be doing wrong.
It seems like you just have the VTK source code but haven't built it yet. VTKConfig.cmake.in is a template used by CMake to generate the VTKConfig.cmake file in the build and install directory. Look at http://www.vtk.org/Wiki/VTK/Building to see how to build VTK.
When you have successfully built VTK you can give CMake a hint where to look for VTK with the VTK_DIR-parameter:
cmake -DVTK_DIR=/path/to/vtk/build-directory /path/to/your/source-directory
If you have successfully built VTK, you would end up with a VTK-Release-build folder containing all the build files, one of which is VTKConfig.cmake. Your program is not able to find this file. You just need to set an environment variable named VTK_DIR before running your program. You can do so by running:
export VTK_DIR=/path/to/VTK-Release-build/
"FindVTK.cmake"the file of cmake is made in build directry.
please add this Path. export VTK_DIR=/path/VTK-Release-version/build
I have found in library Poco under contrib a PocoConfig.cmake which I've copied under /cmake/Modules
I also added in my CMakeLists.txt:
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/")
Now I run under /Build/cmake ..
And I keep getting:
CMake Error at CMakeLists.txt:41 (find_package):
By not providing "FindPoco.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Poco", but
CMake did not find one.
Could not find a package configuration file provided by "Poco" with any of
the following names:
PocoConfig.cmake
poco-config.cmake
Add the installation prefix of "Poco" to CMAKE_PREFIX_PATH or set
"Poco_DIR" to a directory containing one of the above files. If "Poco"
provides a separate development package or SDK, be sure it has been
installed.
Obviously CMake is not finding the module file. What am I doing wrong, how to explicitly point CMake to that module file?
The PocoConfig.cmake doesn't works with find_package (otherwise, it would be named FindPoco.cmake), that's why you're getting this error.
Just include the PocoConfig.cmake in your CMakeLists.txt with:
include(${CMAKE_SOURCE_DIR}/cmake/Modules/PocoConfig.cmake)
I've had similar issues. In my case I was recompiling with an old build folder in place - deleting the folder and recompiling worked.
