Uhm, ist it possible that CMake looks for a CMake configuration file for
perl and not the perl.exe? I get this with your proposal:
CMake Error at CMakeLists.txt:1216 (find_package):
Could not find a package configuration file provided by "Perl" with any of
the following names:
PerlConfig.cmake
perl-config.cmake
Add the installation prefix of "Perl" to CMAKE_PREFIX_PATH or set
"Perl_DIR" to a directory containing one of the above files. If "Perl"
provides a separate development package or SDK, be sure it has been
installed.
