Personally, I'd prefer the latter as it's clean and quite flexible.
I decided to use

P:/mtkLib/Examples/${PROJECT_NAME}/ball.mtk
$TARGET_FILE_DIR:${PROJECT_NAME}

It works fine. But I have a few more questions:
1) How can I get rid of the absolute path in the expression for the
source file?
Use the ${PROJECT_SOURCE_DIR} variable. It points to the directory
containing the CMakeLists.txt file with the last project() call.
2) when doing make clean, the file in the target file dir is not
deleted. How to add it to 'clean'?
See the ADDITIONAL_MAKE_CLEAN_FILES directory property. However, this is
going to be somewhat tricky since you are using $TARGET_FILE_DIR:...
in your custom command, and AFAIK the set_directory_property command is
not aware of this notation. Do you really need ball.mtk to be in the
same directory as your output file?
If one comes to the conclusion that it's worth the effort, one
could also record any additional files to clean at build time
and use a custom target to trigger the built-in clean target
as well as to remove the recorded files:
# CMakeLists.txt:
CMAKE_MINIMUM_REQUIRED(VERSION 2.8 FATAL_ERROR)
PROJECT(P C)
SET(CMAKE_VERBOSE_MAKEFILE ON)
FILE(WRITE ${CMAKE_BINARY_DIR}/f.c void f(void){}\n)
ADD_LIBRARY(f SHARED f.c)
ADD_CUSTOM_COMMAND(TARGET f POST_BUILD
COMMAND ${CMAKE_COMMAND} -E touch $TARGET_FILE_DIR:f/f.dat
COMMAND ${CMAKE_COMMAND}
-DF=$TARGET_FILE_DIR:f/f.dat
-DL=${CMAKE_BINARY_DIR}/files.dat
-P ${CMAKE_SOURCE_DIR}/record.cmake)
FILE(WRITE ${CMAKE_BINARY_DIR}/g.c void g(void){}\n)
ADD_LIBRARY(g SHARED g.c)
ADD_CUSTOM_COMMAND(TARGET g POST_BUILD
COMMAND ${CMAKE_COMMAND} -E touch $TARGET_FILE_DIR:g/g.dat
COMMAND ${CMAKE_COMMAND}
-DF=$TARGET_FILE_DIR:g/g.dat
-DL=${CMAKE_BINARY_DIR}/files.dat
-P ${CMAKE_SOURCE_DIR}/record.cmake)
FILE(WRITE ${CMAKE_BINARY_DIR}/h.c void h(void){}\n)
ADD_LIBRARY(h SHARED h.c)
ADD_CUSTOM_COMMAND(TARGET h POST_BUILD
COMMAND ${CMAKE_COMMAND} -E touch $TARGET_FILE_DIR:h/h.dat
COMMAND ${CMAKE_COMMAND}
-DF=$TARGET_FILE_DIR:h/h.dat
-DL=${CMAKE_BINARY_DIR}/files.dat
-P ${CMAKE_SOURCE_DIR}/record.cmake)
ADD_CUSTOM_TARGET(totalclean
COMMAND ${CMAKE_COMMAND}
--build ${CMAKE_BINARY_DIR}
--config $CONFIGURATION
--target clean
COMMAND ${CMAKE_COMMAND}
-DL=${CMAKE_BINARY_DIR}/files.dat
-P ${CMAKE_SOURCE_DIR}/remove.cmake)
# record.cmake:
IF(EXISTS ${L})
FILE(STRINGS ${L} FILES)
ENDIF()
LIST(APPEND FILES ${F})
LIST(REMOVE_DUPLICATES FILES)
STRING(REGEX REPLACE ; \n FILES ${FILES})
FILE(WRITE ${L} ${FILES}\n)
# remove.cmake:
IF(EXISTS ${L})
FILE(STRINGS ${L} FILES)
FILE(REMOVE ${FILES})
FILE(REMOVE ${L})
ENDIF()
The downside is that one cannot use the well-known clean target
anymore to purge the files but must trigger totalclean instead.

Re: [CMake] Copy a input file from src folder to EXECUTABLE_OUTPUT_PATH
I want to be moved to the same folder as the executables.
How do I do that in CMake?
At configuration time:
CONFIGURE_FILE(path/to/input.txt ${EXECUTABLE_OUTPUT_PATH} COPYONLY)
Note that the destination directory, i.e. the EXECUTABLE_OUTPUT_PATH,
possibly must already exist, and refer to the EXECUTABLE_OUTPUT_PATH
variable only after it has received its value. BTW, this variable is
obsolete, use [CMAKE_]RUNTIME_OUTPUT_DIRECTORY[_CONFIG] variable/
properties instead.
At build time:
ADD_CUSTOM_TARGET(input ${CMAKE_COMMAND} -E copy_if_different
path/to/input.txt ${EXECUTABLE_OUTPUT_PATH})
ADD_DEPENDENCIES(OneOfYourExecutables input)
ADD_DEPENDENCIES(AnotherExecutable input)
or
ADD_CUSTOM_COMMAND(TARGET OneOfYourExecutables
COMMAND ${CMAKE_COMMAND} -E copy_if_different
path/to/input.txt $TARGET_FILE_DIR:OneOfYourExecutables)
ADD_CUSTOM_COMMAND(TARGET AnotherExecutable
COMMAND ${CMAKE_COMMAND} -E copy_if_different
path/to/input.txt $TARGET_FILE_DIR:AnotherExecutable)

Thanks. Great feedback!
