[CMake] How to fetch exit status of INSTALL(CODE ...)

[Marcel Loose]

Hi all,

I have a macro that, during install, compiles python source files to
byte code. Sometimes, there's a syntax error in the python source that
can be caught during compilation; i.e. during the execution of
INSTALL(CODE ...).

Is is possible to somehow fetch the exit status of commands executed
inside INSTALL(CODE ...), so that I can let 'make install' exit with a
non-zero exit status?

Best regards,
Marcel Loose.
