update:

now I have installed bzip2 (and openssl) and provided the related path 
with CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH with the same result. The 
libraries will be taken from the system path.

Additional I have added the CMAKE_..._PATH to 
cmake/modules/FINDBZIP2.cmake to see if this will catch this without 
success.

FIND_PATH(BZIP2_INCLUDE_DIR bzlib.h
    ${CMAKE_INCLUDE_PATH}
  /usr/include
  /usr/local/include
)

FIND_LIBRARY(BZIP2_LIBRARY NAMES bz2 bzip2
  PATHS
    ${CMAKE_LIBRARY_PATH}
  /usr/lib
  /usr/local/lib
)

How to proceed ?
