mir cmake build

My cmake build of the current library failes.
It could not find Boost, GLESv2, Lcov and gcovr.

Could NOT find Lcov (missing: LCOV_EXECUTABLE GENHTML_EXECUTABLE)
Could NOT find gcovr (missing: GCOVR_EXECUTABLE)
CMAKE_C_COMPILER: /usr/bin/cc
CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find GLESv2 (missing: GLESv2_LIBRARY GLESv2_INCLUDE_DIR)
Call Stack (most recent call first):
  /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
  cmake/FindGLESv2.cmake:22 (find_package_handle_standard_args)
  CMakeLists.txt:203 (find_package)

What shall I do?
