Unable to locate libLAS

[rkrug]

Hi

I need your help here - the the build fails, because liblas is not found.

The formula installs fine when omitting the --with-liblas option ( as done in commit 7c020cc just now).

The config log gives the following error message:

checking for liblas-config... /usr/local/opt/liblas/bin/liblas-config
checking for liblas/capi/liblas.h... yes
configure: error: *** Unable to locate libLAS library.

I would assume, that liblas-config provides the correct paths (these are from my local system, where I get the same error):

0:01 $ liblas-config --libs
-L/usr/local/Cellar/liblas/1.8.1_1/lib -llas -llas_c -L/usr/local/lib /usr/local/lib/libboost_program_options-mt.dylib /usr/local/lib/libboost_thread-mt.dylib /usr/local/Cellar/gdal/2.3.1_2/lib/libgdal.dylib /usr/local/lib/libgeotiff.dylib /usr/local/lib/libtiff.dylib

which gives, for the first path,

0:02 $ ls -la /usr/local/Cellar/liblas/1.8.1_1/lib

I have no idea here why it does not find the liblas library (and which file the config is looking for).

Is this a liblas issue, or grass?
