Pcl: Error with FLANN definitions in FindFLANN.cmake

[dooxe]

Hello,

When statically building a fresh-cloned PCL git repo, I get the following error:

[  5%] Building CXX object kdtree/CMakeFiles/pcl_kdtree.dir/src/kdtree_flann.cpp.o
In file included from <built-in>:417:
<command line>:1:9: error: macro name must be an identifier
#define -DFLANN_STATIC 1

It seems to be related to the FLANN definitions in cmake/FindFLANN.cmake file:
https://github.com/PointCloudLibrary/pcl/blob/dd905161a242087a21ef367a6070ee86556ba2ac/cmake/Modules/FindFLANN.cmake#L53

The build is going well by removing -D

Thanks for reporting. Would you mind submitting a pull request with the fix?

No problem, I'll do it as soon as the build is over so that I'm sure the change has no side effect.
