Not yet...with CPackRPM.
Building a source RPM with CMake/CPack is not as easy as building a
binary RPM. Because currently the spec file used to build a binary RPM
is a "short-cutted" one:
- the %prep step is a simple move of directory
- the %build is void (because CMake BUILDTOOL should have already done
the build
- the %install is a simple move too (because CPack did the install
on it's own)
This is due to the fact that when you call CPack,
- CMake has been called
- The software has been built
- CPack will call install for you BEFORE calling the CPackRPM generator
in the end CPackRPM "just" have to package the "already built and
installed file".
In a source RPM you should specify the steps (%prep, %build, %install)
what CMake/CPack usually do. So basically the RPM spec file to use
for building a source RPM won't be the same as the one used to build
the current binary RPM.
So implementing a "Source RPM" generator is doable,
and in fact it was done in the UseRPMTools.cmake macro
http://www.cmake.org/Wiki/CMakeUserUseRPMTools
which is the ancestor of CPackRPM.
The drawback of the old UseRPMTools is that even for a binary RPM
it will redo all the steps including calling CMake etc...
Why do you need to build a Source RPM with CPack ?
What is your usage pattern?
