Why doesn't “CMAKE_MAKE_PROGRAM” variable take effect?

问题

I try to use gmake instead of make as the build command. So I modify the CMakeList.txt as following:

......
set(CMAKE_MAKE_PROGRAM /usr/local/bin/gmake)
......

While in CMakeCache.txt, CMAKE_MAKE_PROGRAM is still /usr/bin/make:

//Path to a program.
CMAKE_MAKE_PROGRAM:FILEPATH=/usr/bin/make

How to make "CMAKE_MAKE_PROGRAM" variable take effect?

回答1:

You have two options:

1: Set the make command when you call CMake: cmake -DCMAKE_MAKE_PROGRAM=gmake <the rest of your arguments>

2: Do as @arrowd hinted in the comments, but use the correct syntax: set(CMAKE_MAKE_PROGRAM gmake CACHE FILEPATH "" FORCE) or set(CMAKE_MAKE_PROGRAM gmake CACHE INTERNAL ""). The latter will hide the setting from cmake-gui.

Both of these assume that gmake is in your PATH, othwerwise you must specify a full path to gmake.
