Re: cmake can't find Xcursor library

[W.D.T Chathurange]

Hello,

I am trying to compile the Allegro 5 game programming library in OpenBSD
7.5 amd64. When I run the cmake command, I get the following error.

-- Looking for XcursorImageCreate in Xcursor
-- Looking for XcursorImageCreate in Xcursor - not found

Make Error at CMakeLists.txt:787 (message):
  X11 support requires Xcursor library

I checked the CMakeLists.txt and as I understand it is trying to find the
Xcursor library. Below is the relevant code snippet.

     check_library_exists(Xcursor XcursorImageCreate "" CAN_XCURSOR)
     if(CAN_XCURSOR)

          set(ALLEGRO_XWINDOWS_WITH_XCURSOR 1)
          find_library(XCURSOR_LIB "Xcursor")

          list(APPEND X11_LIBRARIES "${XCURSOR_LIB}")

      else(CAN_XCURSOR)

          message(FATAL_ERROR "X11 support requires Xcursor library.")

      endif(CAN_XCURSOR)

The Xcursor.h file is present in /usr/X11R6/include/X11/Xcursor/Xcursor.h
and the header file has the XcursorImageCreate function.

I managed to build this in Arch Linux without doing any changes. Not sure
why it can't find the Xcursor in OpenBSD. Any help is much appreciated.

Regards,
Tharindu
