cmake error: Could not find a package configuration file

I am doing autoporting of geogram code using AdaptiveCpp. When executed the cmake command

cmake .. -DGeogram_DIR=/...../geogram/cmake -DAdaptiveCpp_DIR=/...../AdaptiveCpp/lib/cmake/AdaptiveCpp -DACPP_TARGETS='cuda:sm_86'
in geobox/build got the following error:

CMake Error at CMakeLists.txt:6 (find_package):
By not providing "FindGeogram.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Geogram", but
CMake did not find one.

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

GeogramConfig.cmake
geogram-config.cmake

Add the installation prefix of "Geogram" to CMAKE_PREFIX_PATH or set
"Geogram_DIR" to a directory containing one of the above files. If
"Geogram" provides a separate development package or SDK, be sure it has
been installed.
But I have already added the path to FindGeogram.cmake in the cmakelist of geobox using Geogram_DIR and also given the path while running the cmake command. No files named GeogramConfig.cmake or geogram-config.cmake are created.
