[CMake] Re : Re: How to pass a configuration file to CMake?

[Cedric Doucet]

Hello,
I do not manage to pass a configuration file to cmake.

I type 'cmake -C ../config.cmake'

where config.cmake belongs to the parent directory and contains these lines:

set(ENABLE_DOWNLOAD True CACHE BOOL)
set(GCC_ROOT "/local/cdoucet/gcc/4.9.2/" CACHE PATH)

I get the following error message but I don't understand why:

loading initial cache file ../config.cmake
CMake Error at /local/cdoucet/simol/config.cmake:1 (set):
  set given invalid arguments for CACHE mode.


CMake Error at /local/cdoucet/simol/config.cmake:2 (set):
  set given invalid arguments for CACHE mode.


CMake Error: The source directory "/local/cdoucet/simol/config.cmake" is a file, not a directory.


Do you know how to solve this problem?

Hi Cedric.

I have never used it myself, but I believe you're looking for CMake's command-line option '-C <initial-cache>': https://cmake.org/cmake/help/latest/manual/cmake.1.html

Hello,
I would like to know if it's possible to pass a configuration file to CMake.I have to pass a lot of information to CMake and the resulting command line is very long to type.Would it be possible to create a file containing all needed definitions and pass it to CMake?
For exemple, instead of typing
cmake -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=/home/me/there -D CMAKE_CXX_COMPILER=/usr/local/gcc/4.9.3/g++
would it be possible to create a file containing
CMAKE_BUILD_TYPE=DebugCMAKE_INSTALL_PREFIX=/home/me/thereCMAKE_CXX_COMPILER=/usr/local/gcc/4.9.3/g++
and pass it to CMake?
