I have specify ninja path in the MakeFile,it will call meson to build.
And I import cmake in the meson.build to build grpc,
but the cmake cannot find ninja.
Program cmake found: YES (/opt/homebrew/bin/cmake)
error retrieving cmake information: returnCode=255 stdout= stderr=CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
Error: --system-information failed on internal CMake!
Any help will be appriated!

How to install and configure 'cmake' in MSYS2?
I have tried installing the following MSYS packages
I am getting the following error on running any cmake commands
'''
CMake Deprecation Warning at CMakeLists.txt:5 (cmake_minimum_required):

Please help resolve this error.
CMake on Windows tries to use the MSVC compiler by default (cl). To make it use GCC, add following flags: -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++.
You can search for packages on https://packages.msys2.org and find cmake package :
pacman -S cmake
I'm trying to compile MLIR with the command:
cmake -G "Unix Makefiles" -DLLVM_ENABLE_PROJECTS=“mlir” ../mlir
Then came the CMake Error:
...
CMake Error at CMakeLists.txt:10 (tablegen):
Unknown CMake command "tablegen".
Call Stack (most recent call first):

I can't figure out what went wrong, how can I fix it?
Whichever llvm project you want to build, you still need to run cmake for the source directory corresponding to top-level llvm directory, not for its subdirectory.
Top-level directory is where you clone the project https://github.com/llvm/llvm-project.
I'm trying to compile libzip on Windows using CMake to generate makefiles. Libzip needs zlib so I'm doing the following:
mkdir build
cd build
cmake -DZLIB_LIBRARY=../../../zlib-1.2.11 -DZLIB_INCLUDE_DIR=../../../zlib-1.2.11 ..
This doesn't work, however. I get the following error:
CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
Why is that? I have defined ZLIB_LIBRARY and ZLIB_INCLUDE_DIR to point to the latest zlib.
I've also tried the following:
mkdir build
cd build
cmake .. -DZLIB_LIBRARY=../../../zlib-1.2.11 -DZLIB_INCLUDE_DIR=../../../zlib-1.2.11
When I run CMake like this, I get the following two warnings:
CMake Warning:
Manually-specified variables were not used by the project:
ZLIB_INCLUDE_DIR
ZLIB_LIBRARY
In comparison to the first approach, however, build files are now written to my build directory. When running nmake, however, only zlib seems to get built. libzip itself isn't built at all.
I'm out of ideas here. What am I doing wrong?
To answer my own question, using relative paths for ZLIB_LIBRARY and ZLIB_INCLUDE_DIR was the problem. When using absolute paths, it works just fine. Furthermore, ZLIB_LIBRARY needs to point to the library itself. Here is my final build line which works:
cmake -DZLIB_INCLUDE_DIR=d:\mystuff\zlib-1.2.11 -DZLIB_LIBRARY=d:\mystuff\zlib-1.2.11\build\zlibstatic.lib -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=Release ..
I keep getting an error when I try to build yaml-cpp on Windows.
Using the CMake gui application I selected build- and sourcepath correctly, but as soon as I hit the "Configure" Button there is the following error thrown:

I know it has to do with the selected Generator, I selected CodeBlocks - MinGW Makefiles. However I have installed CodeBlocks correctly. So is there perhaps a way to set the CMAKE_MAKE_PROGRAM variable manually?
I would like to force CMake to use the "Unix Makefiles" generator from within CMakeLists.txt.
This is the command I use now.
cmake -G "Unix Makefiles" .
I would like it to be this.
cmake .
When running on windows with VC installed and a custom tool-chain.
I would expect to be-able to set the generator in the CMakeLists.txt file.
Maybe something like this.
set(CMAKE_GENERATOR "Unix Makefiles")
Here is what worked for me - create a file called PreLoad.cmake in your project dir containing this:
set (CMAKE_GENERATOR "Unix Makefiles" CACHE INTERNAL "" FORCE)
It seems to me that the variable CMAKE_GENERATOR is set too late if set in the CMakeLists.txt. If you use (even at the beginning of CMakeLists.txt)
set(CMAKE_GENERATOR "Ninja")
message("generator is set to ${CMAKE_GENERATOR}")
you can see in the output something like
% cmake ../source
-- The C compiler identification is GNU 4.9.2
...
-- Detecting CXX compile features - done
generator is set to Ninja
-- Configuring done
-- Generating done
-- Build files have been written to: /tmp/build
So the variable is only set at the very end of the generation procedure. If you use something like
set(CMAKE_GENERATOR "Ninja" CACHE INTERNAL "" FORCE)
in CMakeLists.txt, then in the very first run of cmake ../source (without -G) the default generator is used. The variable CMAKE_GENERATOR is stored in the cache, though. So if you rerun cmake ../source afterwards, it will use the generator as specified in the CMAKE_GENERATOR variable in the cache.
This is surely not the most elegant solution, though ;-) Maybe use a batch file that will actually execute the cmake -G generator for the user...
This is not what I get, when I run the same command, cmake will look for a gcc compiler / make utility. If the PATH is not set up correctly it will fail with something like:
D:\Development\build>cmake -G "Unix Makefiles" ..\source
CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set.

when gcc / mingw is in the path then everything works fine. So could you provide more information as to your PATH variable or CMAKE version?
You need to set the generator at the Generate stage so it is written into the cache.
You only need to run this command once for the first configuration
cmake .. -DCMAKE_GENERATOR:INTERNAL=Ninja
This will configure Ninja as the default generator.
Later you can simply run
cmake ..
And it would use the Ninja generator as default
You can read more about it under Running CMake from the command line
When running cmake from the command line, it is possible to specify command line options to cmake that will set values in the cache. This is done with a -DVARIABLE:TYPE=VALUE syntax on the command line. This is useful for non-interactive nightly test builds.
CMake 3.19 introduces a new feature - presets. So, to select proper generator automatically, you can specify it name in CMakePresets.json.
