Hello,

I'm trying to compile a project using CEGUI.

I have the FindCEGUI.cmake in place (https://bitbucket.org/cegui/cegui/src/8 ... ew-default).

Here is the lines I have put in my CMakeLists.txt

Code: Select all

find_package(CEGUI REQUIRED)
if (CEGUI_FOUND)
  include_directories(${CEGUI_INCLUDE_DIR})
  target_link_libraries(globularone ${CEGUI_LIBRARIES})
endif()

But when I try to generate my Makefile i got this error:

-- Looking for CEGUI...
-- Could not locate CEGUI
CMake Error at cmake/FindCEGUI.cmake:247 (message):
Required library CEGUI not found! Install the library (including dev
packages) and try again. If the library is already installed, set the
missing variables manually in cmake.
Call Stack (most recent call first):
cmake/FindCEGUI.cmake:490 (findpkg_finish)
CMakeLists.txt:32 (find_package)

I have installed CEGUI with my debian SID package manager (libcegui-mk2-dev).

Any help on this ? I'm pretty confused. I don't understand which "missing variables" I should manually set.

Thanks

Hello, I've also been having this issue with the Debian repo version of CEGUI. Creating a Symbolic link (as mpreisler suggests in the excerpt quoted by Kulik) works, however I wouldn't call that a complete solution. I am not sure if this naming convention for the include directory has to do with Debian naming conventions or if it has to do with the maintainer. Either way I am going to try to add support for Debian for the FindCEGUI.cmake file (seeing that otherwise the people that will be downloading my code with CEGUI will have issues with compiling on Debian systems). Once complete I will probably post it on the forums (if someone hasn't already).

Also, Kulik, thanks for the excerpt, it was hard for me to find where the problem was coming from exactly since the output of CMake was not very detailed.

Okay, so I managed to get the FindCEGUI.cmake from before working, the issue with it is that it makes the include path /usr/include/cegui-0.8.4/CEGUI/ when the CEGUI.h header refers to files such as CEGUI/Affector.h, which means that it does not exist to the compiler. What I did is that I grabbed a FindIrrlicht.cmake and modified it for CEGUI. Here's the link:
