[CMake] 'make package': Is setting generators to different default paths possible?

[Winfried]

It's possible to invoke several CPack generators with one call of 'make
package' by configuring in CMakeLists.txt:
set(CPACK_GENERATOR "STGZ;TGZ;TZ;RPM;DEB")
So far, so good!

A generated package can and shall be relocatable. In other words: You can
determine at package install time, **where** in the file system the content
of the package shall be installed to.
If you install the package without an explicit target location, the default
value is used. Each CPack generator has it's own individual predefined
default value (/usr for RPM, ...).
" This default value may be overwritten from the CMakeLists.txt or the cpack
command line by setting an alternative value.
e.g. set(CPACK_PACKAGING_INSTALL_PREFIX “/opt”) " ( ->doc of
CPACK_PACKAGING_INSTALL_PREFIX)

My question:
It's not unusual that one package has different default locations for
different distributions.
So, is it possible to configure different default locations for RPM and DEB,
so that one call of 'make package' can generate a .rpm package with default
location '/opt/kde3' and a .deb package with default location
'/usr/local/kde' ?

My problem:
When I tried set(CPACK_PACKAGING_INSTALL_PREFIX “/opt/kde3”), 'cmake
-DCMAKE_INSTALL_PREFIX=/opt/kde3 ..' ran normal, but 'make package' aborted
with an error messages (repeated several times):

CMake Error at /usr/share/cmake/Modules/CPackRPM.cmake:623 (file):

set(CPACK_RPM_PACKAGE_LICENSE "${CPACK_RESOURCE_FILE_LICENSE}")

# DEB

INCLUDE(CPack)

Before trying set(CPACK_PACKAGING_INSTALL_PREFIX “/opt/kde3”) I tried
set(CPACK_SET_DESTDIR "ON").
Files in the package were in the right place but I was warned that the
resulting .rpm package isn't relocatable anymore.
