How to force my ros package not using some ROS-provided libs?

Let say I created ros package my_package that depends on library (or package)ext_package version 1. I already installed ext_package as stand-alone on my machine and everything worked fine so far...

Now, I created another new_package but needs to use ext_package provided by ros to read data from topic; need to use bridge. However ROS only provides ext_package V2, which is not compatible with V1. Am getting compilation issues.

So I would have to rewrite completely my_package to accomodate V2.... which would be amazingly tedious.

Thus the question: how to edit CMake file such that my_package uses standalone ext_package locate at ~/PathToLib/ext_package/build?

I already tried something like,

unset(EXT_PACKAGE_CONFIG_PATH CACHE)
 unset(EXT_PACKAGE_DIR CACHE)

 message(STATUS  "...initial CMAKE_PREFIX_PATH:")
 message(STATUS ${CMAKE_PREFIX_PATH})

 set(TMP_PREFIX_PATH ${CMAKE_PREFIX_PATH})
 set(CMAKE_PREFIX_PATH "/home/${usrname}/soft/lib/ext_package/build/installed")

 message(STATUS  "... corrected CMAKE_PREFIX_PATH")
 message(STATUS ${CMAKE_PREFIX_PATH})

  SET (EXT_PACKAGE_ROOT "/home/${usrname}/soft/lib/ext_package/build/installed")
  SET (EXT_PACKAGE_INCLUDE_DIRS "/home/${usrname}/soft/lib/ext_package/build/installed/include")
  SET (EXT_PACKAGE_LIBRARY_DIR "/home/${usrname}/soft/lib/ext_package/build/installed/lib")
find_package(ext_package REQUIRED)

... but without success. Any idea please?

P.S. In my case exta_package is ViSP. I installed version 2.10 as standalone on my machine. Also, am using ROS Kinetic.

Generally your approach makes sense. What errors are you getting? Note that you need to make sure you don't have any dependencies on ROS packages with dependencies on ext_packagev2

No error, just that the compiler still uses the version provided by ROS rather than the standalone version I installed from source.
