I have the LLVM source and I was trying to build it from source the following build script gives me errors, what is wrong with the script, It is very likely that build script has errors in it because no one place was able to give me the correct sequence. I tried making use of the syntax given by official llvm site cmake -G -DCMAKE_BUILD_TYPE= [options] ../llvm
llvm official but it doesn't help.

I'm following this tutorial for building GLFW on Windows, and I'm getting the error when running cmake -S . -B Build:
PS ~\glfw-3.3.2\GLFW> cmake -S . -B Build
CMake Error at CMakeLists.txt:3 (project):
Running
'nmake' '-?'
failed with:
The system cannot find the file specified
-- Configuring incomplete, errors occurred!
See also "~/glfw-3.3.2/GLFW/Build/CMakeFiles/CMakeOutput.log".
Output log is almost completely empty containing only one line with my windows version.
I haven't found any discussions or problems matching mine. And I don't even know does nmake have -? flag since it's not listed on microsoft docs site.
I've tried positioning in other folder because maybe that's the case. But with no luck.
I tried solving it with other error solution's but to no avail.
The solution was to append -G "MinGW Makefiles" to cmake -S . -B Build command. As Tsyvarev suggested I looked more into generators and found out that setting the flags doesn't imply which generator will be used. So manually setting the flags solved the problem for me.
The error is about absent nmake utility, which is a build tool for CMake projects configured with "NMake Makefiles" generator.
You need either to install nmake, or specify (with -G option) other generator, which is available on your platform (Windows) and for which you have a built tool. Possible selection of other generators includes e.g. "MinGW Makefiles" and "Visual Studio" family.
This question is about the CMake Tools extension for VS Code. The operation system is Windows 10.
The extension correctly found GCC, which I can verify by having a look at the %LocalAppData%/CMakeTools/cmake-tools-kits.json.
{
"name": "GCC 10.3.0 x86_64-w64-mingw32",
"compilers": {
"C": "C:\\msys64\\mingw64\\bin\\x86_64-w64-mingw32-gcc.exe",
"CXX": "C:\\msys64\\mingw64\\bin\\x86_64-w64-mingw32-g++.exe"
}
}
I tried to configure through the respective VS Code command and got an error:
[rollbar] Unhandled exception: Unhandled Promise rejection: configure Error: No usable generator found. {}
Then I added the respective setting to my local settings .vscode/settings.json.
{ "cmake.generator": "MSYS Makefiles" }
I got the following output:
[proc] Executing command: "C:/Program Files/CMake/bin/cmake.exe" --no-warn-unused-cli -DCMAKE_EXPORT_COMPILE_COMMANDS:BOOL=TRUE -DCMAKE_BUILD_TYPE:STRING=Debug -DCMAKE_C_COMPILER:FILEPATH=C:\msys64\mingw64\bin\x86_64-w64-mingw32-gcc.exe -DCMAKE_CXX_COMPILER:FILEPATH=C:\msys64\mingw64\bin\x86_64-w64-mingw32-g++.exe -H<path to project root> -B<path to build directory> -G "MSYS Makefiles"
[cmake] Not searching for unused variables given on the command line.
[cmake] CMake Error: CMake was unable to find a build program corresponding to "MSYS Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
[cmake] CMake Error: CMake was unable to find a build program corresponding to "MSYS Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
[cmake] CMake Error: CMAKE_AR was not found, please set to archive program.
[cmake] -- Configuring incomplete, errors occurred!
So I extended my local settings.
{
"cmake.generator": "MSYS Makefiles",
"cmake.environment": {
"CMAKE_AR": "C:/msys64/usr/bin/ar.exe",
"CMAKE_MAKE_PROGRAM": "C:/msys64/usr/bin/make.exe"
}
}
Got the same output as before. I also tried setting these variables in the CMakeLists.txt and as system environment variables.
What is the proper way to do this?
I know this is an old request, but I've recently been suffering from this issue.
The trick I found (with the current version of MSYS2 on Windows), was to install the cmake version of mingw64.
With command:
pacman -S mingw-w64-x86_64-cmake
NOTE: This assumes that pacman is defined in your path, otherwise you will need to prefix the pacman with the path.
Then install Ninja:
pacman -S ninja
You shouldn't need to define the configuration in VSCode settings, it should just work.
I am getting the following error :
CMake Error at CMakeLists.txt:9 (BISON_TARGET):
Unknown CMake command "BISON_TARGET".
when I run the command :
cmake .. -GNinja
Please tell me what to do. I tried searching on google a lot and thus came up with the additions and finally ran the command :
cmake .. -D LLVM_DIR=/usr/lib/llvm-5.0/cmake/ -D FLEX_EXECUTABLE=/usr/local/Cellar/flex/2.5.37/bin/ -D FLEX_INCLUDE_DIR=/usr/local/Cellar/flex/2.5.37/include/ -D BISON_EXECUTABLE=/usr/bin/bison
but it still shows the same error :(.
Please someone help.
Your error is occurring because the BISON_TARGET function definition has not yet been supplied. This method, as commented, is supplied by FindBISON. The error indicates that either Bison was not found on your system (hopefully, you have it installed), or cmake was ran from the wrong directory. Bison is included in the top-level CMake file via:
find_package(BISON REQUIRED)
This line to include Bison must be called before using the BISON_TARGET CMake function. The LLReve instructions for compiling this repository are explicit about which directory to run the build commands in:
Go to the llreve directory and run
cd reve
mkdir build
cd build
cmake .. -GNinja
ninja
This would run on the CMake file in the llreve/reve directory, not the llreve/reve/reve directory. Please ensure you are running CMake from the correct location, as not running cmake on the top-level CMake file will often yield errors.
When I create new project in Clion, cmake cannot find CMakeTmp directory.

Any help or directions appreciated, thanks!
The error message
CMake Error: Generator: execution of make failed.
signals, that something wrong with CMake settings or its generator.
In the given case you have additional message
Make command was: /usr/bin/cmake cmTC_df723/fast &&
which means that cmake is run as a Make command.
This is wrong: cmake and make commands are not interchangeable.
Would you inspect the very first command line, you will find the source of that problem:
-DCMAKE_MAKE_PROGRAM=/usr/bin/cmake
Exactly it sets cmake executable for Make command. You need to fix that line (e.g. in CLion settings).
For a new project we want to use CMake. We are using Eclipse CDT as IDE and Cygwin gcc.
We generated the CMakeLists.txt and followed [this tutorial (option 2)][1].
When I try to run the described Make target to generate the Makefiles with CMake, which executes
cmake -E chdir C:/projects/eclipse_ws/MyApp/Build/ cmake -G "Unix Makefiles" ../ Run CMake
I get the error
CMake Error: The source directory "C:/projects/eclipse_ws/MyApp/Build/CMake" does not exist.
If I run the command directly from a Cygwin console it works just fine, however then I have to run make also from the Cygwin console, because the Makefiles are generated with Unix paths.
EDIT:
So I fixed this issue (see my answer below).
But I'm still having problems.
When I try to run CMake as Make target in Eclipse as suggested in the tutorial I get the following errors:

Seems like for some reason CMake assumes I have an MinGW environment and not Cygwin.
EDIT2
MinGW system was assumed, because a Git installation was in PATH before Cygwin and Git's uname command was used (which returns MinGW).
If you check "Make Target - Same as the target name" in Eclipse's Make dialog, Eclipse will add a
Run CMake
to the command (see question), which is misinterpreted by CMake.
I just unchecked "Same as the target name".
