Converting a Makefile project to Cmake

Converting a Makefile project to Cmake

I'm learning how to use cmake for this class but the documentation is
extremely verbose and dense. A lot of the tutorials are either too simple
to be useful (cmake with just one file) or too complicated.
the original Makefile for the project looks like:
# Some optimization settings
# see: http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html
# Standard all target
all: hw1_p2
# Simple program to do brute-force k-nearest neighbor searches against a
signature file
hw1_p2: prob2.o ParseRecord.o Sorter.o Timing.o
g++ -o hw1_p2 prob2.o ParseRecord.o Sorter.o Timing.o
prob2.o: prob2.cpp utility_templates.hpp
g++ -Wall -c prob2.cpp
ParseRecord.o: ParseRecord.cpp ParseRecord.hpp utility_templates.hpp
g++ -Wall -c ParseRecord.cpp
Sorter.o: Sorter.cpp Sorter.hpp
g++ -Wall -c Sorter.cpp
# Timing class
Timing.o: Timing.hpp Timing.cpp
g++ -Wall -c Timing.cpp
# Clean code-derived files
clean:
rm -f *.o hw1_p2
The project is organized like this
cmakelearn
CMakeLists.txt
build
src
CMakeLists.txt
ParseRecord.hpp
Timing.cpp
small.dat
Makefile
Sorter.cpp
Timing.hpp
utility_templates.hpp
ParseRecord.cpp
Sorter.hpp
prob2.cpp
So far, from the reading that I've done I understand that you need a
CMakelists.txt file in every directory. The build folder is there so that
I can go into it and run cmake ..
In the top-level CMakelists.txt file I have
cmake_minimum_required (VERSION 2.6)
project (CMAKETEST)
add_subdirectory(src)
and in the src dir CMakelist.txt here is my attempt:
include_directories(${CMAKETEST_SOURCE_DIR}/src)
link_directories(${CMAKETEST_BINARY_DIR}/src)
add_executable(Timing Timing.cpp)
add_executable(Sorter Sorter.cpp)
add_executable(ParseRecord ParseRecord.cpp)
add_executable(prob2 prob2.cpp)
I don't even really know where to begin other than that. This comment from
a tutorial pretty much sums up my thoughts about cmake and the
documentation right now:
Not nearly detailed enough to be useful. Having said that, I don't like
CMake much anyway; too many separate, arbitrary Things you Just Have to
Know. At least that's my impression. Like, 'add_definitions(-std=c99)'.
Really? Does that name jump out at you as how to add flags to a compiler?
And is 'set(VAR a b c)' any more intuitive than VAR=a b c or some such?
Beh on the article, and on CMake. Yet I know CMake is taking the
build-world by storm.
Still, I really want to learn and figure this out so any help that you can
provide will be much appreciated and helpful. Thanks in advance.
