Hi all,
I've noticed a problematic behaviour with the FIND_XXX macros when using
ENV in either PATHS or HINTS: symbolic links get converted to the real
paths. This happens with cmake 2.6.x and 2.8.0. Is this a bug?
Here's an example:
$ ls -l /opt/hdf5
lrwxrwxrwx 1 root root 18 2009-09-21 10:08 /opt/hdf5 ->
/data/sys/opt/hdf5
$ cat CMakeLists.txt
cmake_minimum_required(VERSION 2.6)
project(MyHDF5)
set(ENV{HDF5_ROOT} /opt/hdf5)
find_path(HDF5_INCLUDE_DIR hdf5.h
HINTS ENV HDF5_ROOT
PATH_SUFFIXES include)
$ grep HDF5_INCLUDE_DIR CMakeCache.txt
HDF5_INCLUDE_DIR:PATH=/data/sys/opt/hdf5/include
Replacing 'ENV HDF5_ROOT' in find_path() with the literal string
'/opt/hdf5' gives me:
$ grep HDF5_INCLUDE_DIR CMakeCache.txt
HDF5_INCLUDE_DIR:PATH=/opt/hdf5/include
Best regards,
Marcel Loose.
