Build failure on latest macOS/XCode
On macOS 11.3/Intel, updated 4/27/2021.

Thank you very much for your report!
This is only a question and has nothing to do with the build issue: you
write "macOS/XCode" but you're using cmake + make to build FLTK. I
assume you installed Xcode to get the build tools but in your build
you're using make (not Xcode). Right?
using 1.3.6RC1 download
$ tar -jxvf fltk-1.3.6rc1-source.tar.bz2
$ cd fltk-1.3.6rc1
$ mkdir build && cd build
$ cmake ..
$ make

This is a silly error, I assume depending on the compiler and case
sensitivity of the file system.
Question: is your file system case sensitive or not?
This is only for (my) info, but it can make a difference and I'd like to
know if this is the case. On my system (Big Sur on Apple Silicon (M1))
with a case /sensitive/ file system the error doesn't appear but it can
also depend on the compiler tools.
Anyway, the fault is that in this scenario the source directory is used
as one of the '-I' commandline switches and it happens that
#include <version>
in one or more system headers erroneously includes the file 'VERSION'
whose contents is "1.3.6" and compilation fails.
Solution: please rename the file 'VERSION' to 'fltk_version.dat' as it
is in 1.4.0 development (git master). There was a reported issue but I
renamed that file only in 1.4.0 and not in branch-1.3. :-(
happy to try anything else that might help.
Could you please try to build again (or just restart the build) after
renaming that file?
TIA, Albrecht
