This flag does not exist for PGI Fortran Compiler.
I have checked this with pgf77, pgf90 and pgfortran.
The only workaround I found is to set the flag:
-DCMAKE_Fortran_FLAGS="-noswitcherror"
This turns off the check for flag validity in the compiler, but obviously is not a long-term solution, since now any test to compiler flags will pass irrespectively if the flag is recognised or not.
The solution I think is changing Modules/Platform/Linux-PGI.cmake to:
set(CMAKE_${lang}_COMPILE_OPTIONS_PIE "")
Note that the flag -fPIE also does not exist for PGI C and C++ compilers.
cmake -DCMAKE_Fortran_COMPILER=pgf90 ..
The man page of compiler does not reference this flag whatsoever.
This is the output I get:
-- The C compiler identification is GNU 4.8.1
-- Check for working C compiler: /usr/bin/gcc

It fails with the following output:
