Unable to install the package for Ros indigo

[ulkesh11]

After git cloning the package with appropriate branch, I tried to do catkin_make but got the following error.

Could not find a package configuration file provided by "app_manager" with
any of the following names:

app_managerConfig.cmake
app_manager-config.cmake

Add the installation prefix of "app_manager" to CMAKE_PREFIX_PATH or set
"app_manager_DIR" to a directory containing one of the above files. If
"app_manager" provides a separate development package or SDK, be sure it
has been installed.
Call Stack (most recent call first):
pr2_apps/pr2_app_manager/CMakeLists.txt:3 (find_package)

Please HELP
