after a fresh git pull did see the CmakeLists.txt file is diffrent.
As suggested in the workaround the following code

 # Extract version of libjpeg so that we can use the appropriate dir
 # See bug #227313, #228483
FILE(READ "${JPEG_INCLUDE_DIR}/jpeglib.h" jpeglib_h_content)
FILE(READ "${JPEG_INCLUDE_DIR}/jconfig.h" jpeglib_h_content)
STRING(REGEX REPLACE ".*#define +JPEG_LIB_VERSION +([0-9]+).*" "\\1"
jpeglib_version "${jpeglib_h_content}")
MESSAGE(STATUS "Identified libjpeg version: ${jpeglib_version}")

cmake -DCMAKE_BUILD_TYPE=release -DCMAKE_INSTALL_PREFIX=`kde4-config
--prefix` .. failed

did a minor change to the code ...

FILE(READ "${JPEG_INCLUDE_DIR}/usr/include/jpeglib.h" jpeglib_h_content)
FILE(READ "${JPEG_INCLUDE_DIR}/usr/include/jconfig.h" jpeglib_h_content)
STRING(REGEX REPLACE ".*#define +JPEG_LIB_VERSION +([0-9]+).*" "\\1"
jpeglib_version "${jpeglib_h_content}")
MESSAGE(STATUS "Identified libjpeg version: ${jpeglib_version}")

-know it is hard coded but works for now ...

cmake -DCMAKE_BUILD_TYPE=release -DCMAKE_INSTALL_PREFIX=`kde4-config
--prefix` ..

no extra C/C++ flags passed this time, making a release build

- kipi-plugins 2.0.0-rc dependencies results <http://www.kipi-plugins.org/>
-- libjpeg library found.................... YES

Linking CXX executable digikam
[100%] Built target digikam

showfoto build size 352,432
digikam build size 6,446,367

JPEGs loads in image editor (verified by using 5 different camera make and
models)

To do ---

one more build to be be tested as by default, `make install' for jpeg-turbo
will install all the files in `/opt/libjpeg-turbo/bin',
`/opt/libjpeg-turbo/lib' etc.
You can specify an installation prefix other than `/opt/libjpeg-turbo' using
`--prefix',
for instance `--prefix=$HOME'.

build a custom libjpeg-turbo-1.1.1 with -prefix=/usr/local and test it out.
More testing need to be done to verify if this works on all Fedora 14 and
later.
