After installing all the required dependencies, we started to build kdevelop using the command:
kdesrc-build --debug libkomparediff2 grantlee kdevplatform kdevelop-pg-qt kdevelop.

However, we received the following error log:

CMake Warning at documentation/CMakeLists.txt:1 (find_package):
By not providing "FindQt5Help.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Qt5Help", but
CMake did not find one.

Could not find a package configuration file provided by "Qt5Help" with any
of the following names:

Qt5HelpConfig.cmake
qt5help-config.cmake

Add the installation prefix of "Qt5Help" to CMAKE_PREFIX_PATH or set
"Qt5Help_DIR" to a directory containing one of the above files. If
"Qt5Help" provides a separate development package or SDK, be sure it has
been installed.


CMake Warning at utils/CMakeLists.txt:1 (find_package):
By not providing "FindOktetaKastenControllers.cmake" in CMAKE_MODULE_PATH
this project has asked CMake to find a package configuration file provided
by "OktetaKastenControllers", but CMake did not find one.

Could not find a package configuration file provided by
"OktetaKastenControllers" (requested version 0.3.1) with any of the
following names:

OktetaKastenControllersConfig.cmake
oktetakastencontrollers-config.cmake

Add the installation prefix of "OktetaKastenControllers" to
CMAKE_PREFIX_PATH or set "OktetaKastenControllers_DIR" to a directory
containing one of the above files. If "OktetaKastenControllers" provides a
separate development package or SDK, be sure it has been installed.

Are these configuration files required or building kdevelop. Is there any work around for this.

Thanks.

Try installing okteta and Qt5 Help (qt5-tools package here).

@reporter: Note this is just a *warning* from CMake, it's not an error. Those dependencies are optional.
