问题 When I start Qt Creator (4.3) and load a session (or a project already configured), CMake is always run at least once. Even if I disabled the autorun of CMake as said in this answer. The cache is already there because I manually run CMake when needed. How can I make Qt Creator to never run CMake automatically ? 回答1: You can't. Qt Creator 4.3 uses cmake server-mode to get information out of cmake. For that it needs to start cmake, which in turn will need to configure and generate to fetch all

问题 I am trying to make a cross-platform CMake for my project (Windows and Linux). I need to use external libraries (yaml-cpp). On Linux, I just had to do an apt get and use find_package . But on Windows, I need to append the CMAKE_MODULE_PATH in order for my program to find the yaml-cpp-config.cmake . So I start by installing yaml-cpp (https://github.com/jbeder/yaml-cpp) with CMake GUI 3.16 and mingw32 ( mingw32-make install ). I have tried the library on a hello world project, and it works fine

问题 I try to build and install the LLVM source on Windows (specifically LLVM-8, but the issue exists on the latest version as well), using Visual Studio 2019 and CMake 3.18.2, following the guide from http://llvm.org/docs/GettingStarted.html#getting-the-source-code-and-building-llvm. The output however looks the same as discussed in Building LLVM using Visual Studio, but the solution did not change anything for me. I ran the following commands: git clone --config core.autocrlf=false https:/

问题 I Try to build an application using Qwt with CMake on a MacOS virtual machine. I installed Qt5 and Qwt using brew: brew install qt5 qwt The result is a Qwt framework installation.

问题 When using CMakeLists to compile an OpenGL project, I have the following line to link glut and gl: target_link_libraries(my_exe ${OPENGL_gl_LIBRARY} ${GLUT_LIBRARIES}) I looked up how to link glut and gl with CMake so I saw that I could use ${OPENGL_gl_LIBRARY} and ${GLUT_LIBRARIES}. But how would I know the variables to use otherwise? I am used to just doing ${THELIBRARY_LIBRARES}, but in the case of gl, it changed to adding that " gl " into the variable name. How would I know that without
