Passing FreeImage to cmake

[fanou]

hi,

I'm trying to compile Lux v0.9 on SLES11 (Suse Linux Enterprise Server 11) SP1.
FreeImage is not available and I compiled it from sources.

But cmake cannot find it. I tried to declare FREEIMAGE_INCLUDE_PATH and FREEIMAGE_LIBRARY, but I still get the following message :

package 'freeimage' not found

How can I tell cmake where is my FreeImage library ?

Thanks

On windows I simply do

Code: Select all

SET(FREEIMAGE_ROOT            "${DEPS_ROOT}/FreeImage3141/FreeImage")

where "DEPS_ROOT" is my own variable of where my dependencies are.

Thanks.

Code: Select all

FREEIMAGE_ROOT

seems to be used only for Windows.
But I used your tip and set :

Code: Select all

SET(FreeImage_INCLUDE_DIR "${LUX_BUILD}/FreeImage/Dist")
SET(FreeImage_LIBRARY_DBG "${LUX_BUILD}/FreeImage/Dist")
SET(FreeImage_LIBRARY_REL "${LUX_BUILD}/FreeImage/Dist")


Building on RHEL or SLES is long as most of lux dependencies are not available, or too old.
For example, boost is installed with 1.36.0 only. I recompiled with 1.46.1.

Hi,

There's nothing Windows specific in the FreeImage detection, so FREEIMAGE_ROOT should work on any platform.

Hi,

I'm not familiar to cmake, so sorry if I'm wrong but,
what I understand of this code in luxrays/cmake/Packages/FindFreeImage.cmake is that FREEIMAGE_ROOT_DIR seems to be used only for WIN32, or not ?
That's why I declared FREEIMAGE_INCLUDE_PATH and FREEIMAGE_LIBRARY.

FREEIMAGE_ROOT is never used in v0.8.

Code: Select all

IF (WIN32)
    FIND_PATH( FREEIMAGE_INCLUDE_PATH FreeImage.h
        ${FREEIMAGE_ROOT_DIR}/include
        ${FREEIMAGE_ROOT_DIR}
        DOC "The directory where FreeImage.h resides")
    FIND_LIBRARY( FREEIMAGE_LIBRARY
        NAMES FreeImage freeimage
        PATHS
        ${FREEIMAGE_ROOT_DIR}/lib
        ${FREEIMAGE_ROOT_DIR}
ELSE (WIN32)
    FIND_PATH( FREEIMAGE_INCLUDE_PATH FreeImage.h
        /usr/include
        /usr/local/include
        /sw/include
        /opt/local/include
        DOC "The directory where FreeImage.h resides")
    FIND_LIBRARY( FREEIMAGE_LIBRARY
        NAMES FreeImage freeimage libfreeimage libfreeimage-3.15.2
        PATHS
        /usr/lib64
        /usr/lib
        /usr/local/lib64
        /usr/local/lib
        /sw/lib
        /opt/local/lib
        DOC "The FreeImage library")
ENDIF (WIN32)

Hi,

You said Lux, so I answered for the renderer, the luxrays cmake opencl detection needs to be updated to match what we have in lux. If you define the variables, it should work though.

Ok, yes.
I was talking about luxrays which I was compiling first.
