[CMake] Selecting DEBUG and RELEASE Builds in Linux

[BlinkEye]

I guess you missed my answer yesterday ...

If I'm not mistaken calling just cmake path_to_your_project_srcs doesn't set the
BUILD_TYPE to anything.

What about the following:

% cd build/your_project/debug;
% cmake path_to_project_srcs -DCMAKE_BUILD_TYPE=DEBUG

% cd build/your_project/release
% cmake path_to_project_srcs -DCMAKE_BUILD_TYPE=RELEASE

You could easily create aliases for these 2 commands, like:

alias cmakedebug='cmake $1 -DCMAKE_BUILD_TYPE=DEBUG'
alias cmakerelease='cmake $1 -DCMAKE_BUILD_TYPE=RELEASE'

which would be used like:

% cd build/your_project/debug
% cmakedebug path_to_project_srcs

or

% cd build/your_project/release
% cmakerelease path_to_project_srcs

respectively.

To set a default build type I suggest the following:

if( NOT CMAKE_BUILD_TYPE )
  set( CMAKE_BUILD_TYPE Debug CACHE STRING
       "Choose the type of build, options are: None Debug Release RelWithDebInfo
MinSizeRel."
       FORCE )
endif()

This will just overwrite the CMAKE_BUILD_TYPE if it has not been set.
