Earlier I wondered if there was a way to stop recusive invocation of a
build command in a cmake script - I found something like a solution;
when I run the command, set an environment variable and don't run the
command if that environment variable is set... But...
If I specify 'TARGET' in BUILD_COMMAND, then it gets extra quotes
around it, which make it impossible to pass to execute_process. Also
why doesn't cmake-gui run certain commands?
------example - probably incomplete -----------
PROJECT( whatever )
build_command( GENERATOR_BUILD_COMMAND CONFIGURATION
${CMAKE_BUILD_TYPE} PROJECT_NAME ${PROJECT_NAME} TARGET all )
message( "build command:${GENERATOR_BUILD_COMMAND}" )
--------- output -------
build command:e:/tools/unix/mingw/bin/mingw32-make.exe -i "all"
mingw32-make.exe: *** No rule to make target `"all"'. Stop.
---end output, begin explanation--------
In order to get BUILD_COMMAND output to work at all I have to
STRING( REPLACE "\ " ";" GENERATOR_BUILD_COMMAND
${GENERATOR_BUILD_COMMAND} )
which replaces the spaces in the command with semicolons, so it looks
like seperate commands for
EXECUTE_PROCESS(COMMAND ${GENERATOR_BUILD_COMMAND}
WORKING_DIRECTORY ${CMAKE_BINARY_DIR} )
and in cmake-gui the output looks something like
---
build command:e:/tools/unix/mingw/bin/mingw32-make.exe -i "all"
Executing command... (output just before Execute_process)
Configuring done
---
but the command is never actually executed? I go out to a command
line and type cmake . and the build goes.
