Hi QP,
Probably not the intended solution, but what I’m doing in such cases is that in
a patch step I create a shell script that does the configuration for me. With
all the environment settings and everything. Like:
PATCH_COMMAND ${CMAKE_COMMAND} -E echo “cd someDir/; CC=\”something\”
./configure” > configure.sh
CONFIGURE_COMMAND sh configure.sh
Unfortunately this makes the code quite unportable, as it will only work on
POSIX platforms like this. But I guess that’s the case anyway once you start
setting environment variables.
Cheers,
Attila
P.S. I often create build.sh and install.sh scripts as well in additional patch
commands.
