cmake: Selecting a generator within CMakeLists.txt

Question

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")

Answer 1

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)
