Description Yuri Victorovich freebsd_committer 2020-01-03 21:54:59 UTC
> find_path(FLEX_INCLUDE_DIR FlexLexer.h
>  DOC "Path to the flex headers")

can never find port's FlexLexer.h that is installed into /usr/local/include/flex/FlexLexer.h

Ports should use flex from ports, not from the base, because port have a generally newer version.

The above place in share/cmake/Modules/FindFLEX.cmake should be:
> find_path(FLEX_INCLUDE_DIR flex/FlexLexer.h
>  DOC "Path to the flex headers")

Moin moin 

Sorry, I overlooked this PR.

We could add some path hints to make it also look in localbase too for headers and libraries of flex.
Do you have a port in mind to test it against?

Comment 2 Yuri Victorovich freebsd_committer 2020-01-19 07:54:51 UTC
The port is cad/cascade-compiler.

files/patch-CMakeLists.txt removes FLEX_INCLUDE_DIRS because it is wrong (not from ports).

Could you try the attached patch to devel/cmake?

Comment 4 Yuri Victorovich freebsd_committer 2020-01-19 09:22:04 UTC
Now FLEX_INCLUDE_DIRS=/usr/local/include/flex.

Thank you for working on this!
