I want to point to a local directory for Sophus which has se3.h instead of se3.hpp. The path I am specifying does have the correct header.

I set the find_package as follows.

findpackage(Sophus REQUIRED NOSYSTEMENVIRONMENTPATHNOCMAKEPATH NOCMAKESYSTEMPATH NODEFAULTPATH REQUIRED PATHS /home/rjn/catkinws/rpg/Sophus)

as you can see I have tried just about every thing allowed to stop cmake from using the system lib. But I still get the error:

In file included from /home/rjn/catkinws/src/rpgros/rpgvikit/vikitcommon/src/mathutils.cpp:8:0: /home/rjn/catkinws/src/rpgros/rpgvikit/vikitcommon/include/vikit/mathutils.h:14:24: fatal error: sophus/se3.h: No such file or directory compilation terminated.

The only thing that seems to work is if I hard code the paths in both, this seem like a hack

INCLUDEDIRECTORIES and TARGETLINKLIBRARIES(${PROJECTNAME}
