[CMake] Re: cmake 2.2: make install PREFIX not working with CMAKE_INSTALL_PREFIX set to "/"

[Michael Biebl]

It's getting stranger and stranger.
As I wanted to avoid that cmake generates "//" at the beginning of the
path name, I used
SET(CMAKE_INSTALL_PREFIX "" CACHE INTERNAL "")
Now, the following install command
INSTALL_FILES(/foo/bar FILES dir/test1)
installs on "make install DESTDIR=/tmp" the file
into /tmp/usr/local/foo/bar/dir/test1 (note the "/usr/local")
whereas
INSTALL_FILES(/foo/bar FILES test2) installs as expected to
/tmp/foo/bar/test2

This is really getting weird.

Hope, someone can help me with this problem.

Cheers,
Michael
