Hi guys,
I am using Rational Purify for runtime error checks in C++. To use it, you have
to call purify instead of the C++ linker at link phase. To do so, I have the
following cmake file:
//------------
project(myproject )
option (USE_PURIFY "Use Rational Purify for runtime error checks" OFF)
IF (USE_PURIFY)
set(CMAKE_CXX_LINK_EXECUTABLE "purify ${CMAKE_CXX_LINK_EXECUTABLE}")
ENDIF (USE_PURIFY)
add_executable (myproject HelloWorld.cc)
//------------
This adds the option and changes the linker (prepending with "purify"). This
works fine.
Now I would like to trigger the IF() line from a make target. Say, when I type
"make myproject_purify", I would like to set the option (or prepend the linker,
whichever is best).
I am quite uncertain how to do it with cmake. I did not find any hint if I can
set options from cmake itself or not. Also, whenever I define a new make
target, I have to supply a shell command and it seems I cannot execute cmake
commands there.
So my question: how would you set an option via a make target? Any hints?
Thanks,
Mc
