This option controls how the compiler searches for implicit include files for templates in C++.

When the option --implicit_include_searches is selected, the compiler uses the search path to look for implicit include files based on partial names of the form filename.*. The search path is determined by -I, -J, the ARMCCnINC environment variable and the ARMINC environment variable. The search path also includes the default ../include directory if -J, ARMCCnINC, and ARMINC are not set.

When the option --no_implicit_include_searches is selected, the compiler looks for implicit include files based on the full names of files, including path names.
