Yes I meant highest level.

Right now I am using the subdir logic (from the past where there were
more c projects and the py project was a c project). So no problem with
that but I never successfully used the command by myself. I tried it
right now with the following two possibilities:

in the highest level CMakeLists.txt:
add_subdirectroy(pyProject)
add_subdirectroy(cProject)

first try:

ADD_CUSTOM_TARGET(pyCustom COMMAND ${PYTHON_EXECUTABLE} -O -c "import
compileall; compileall.compile_dir('./pyProject/', maxlevels=0, force=1);"
	DEPENDS cProject/cbin
)

results into a clean build but no pyc files and no /usr/bin/python in
the Makefiles

second try:
ADD_CUSTOM_TARGET(pyCustom ALL COMMAND ${PYTHON_EXECUTABLE} -O -c
"import compileall; compileall.compile_dir('./pyProject/', maxlevels=0,
force=1);"
	DEPENDS cProject/cbin
)

gives me the following errors (make VERBOSE=1)

/usr/bin/python -O -c import\ compileall;\
compileall.compile_dir('./pyProject/',\ maxlevels=0,\ force=1);
/bin/sh: -c: line 0: syntax error near unexpected token
`'./pyProject/',\ maxlevels=0,\ force=1'
/bin/sh: -c: line 0: `/usr/bin/python -O -c import\ compileall;\
compileall.compile_dir('./pyProject/',\ maxlevels=0,\ force=1);'
