Hi Mark,

Sorry about that, it seems that on our systems we have installed the
laslib headers to /usr/local/include/laslib. Problematically, both
programs I think expect the headers to be in the format laslib/*.hpp,
I'm not sure yet whether that's specific to our system and we should
change the program to ignore the "laslib/" prefix, so that the configure
script can be configured to point the compiler to any old directory, or
whether there is some conventional way of installing laslib that we've
followed. I'm afraid Mike, who would know, is away until Tuesday, so I
can't say for sure.

Your options are to either wait for me to find out and I will set it up
how it should be, (configure already points the compiler at both
/usr/local/include and /usr/local/include/laslib, so you or I should be
able to change any of the include statements over without trouble) OR
you can work around it for now if you don't mind the hassle.

To work around it, either copy the headers to
/usr/local/include/laslib/, or copy them to some local location you'll
remember to delete, and as long as they're in a folder called laslib,
you'll be able to point the compiler to the parent folder with:

export laslib_CFLAGS=-I/path/to/folder # where folder contains laslib/*.hpp
export laslib_LIBS=-L/path/to/object/files -llaslib
./configure

I'm concerned that our .pc files for laslib are our own version and that
there is no official version. I will get back to you on Tuesday with
more details on that.

If it were useful to enough people, I could potentially be persuaded to work out how to build packages for some Linux package managers too.
