Making a CMakeLists.txt

[roelj]

I'm trying to convert my Makefile to a CMakeLists.txt so that I can compile on Windows and Mac computers too.
I haven't found answers to all of my questions, so I hope somebody can help me.

Here's my Makefile:

#
#  Copyright (C) 2011, 2012  Roel Janssen <roel@moefel.org>
# ... GPLv3 or later copyright notice ...
# 

## The compiler command used to compile the stuff.
CC              = g++

## Required Boost libraries to build this application.
BOOST_STUFF     = -lboost_filesystem -lboost_system -lssl -lcrypto -pthread

## The Botan library is needed for the SHA-256 algorithm.
BOTAN_STUFF     = -lbotan

## Choose your prefered database back-end.
## Please note that you need to compile cppdb with support for this driver.
## Add either -lcppdb_postgresql, -lcppdb_sqlite3 or -lcppdb_mysql to DB_BACKENDS
DB_BACKENDS	= -lcppdb_sqlite3
DATABASE_STUFF  = -lcppdb $(DB_BACKENDS) -ldl

BUILD_TARGET    = build/Distributor
OPTIMIZATION    = -Wall -Wextra -Os

## A list of all objects.
# Left out: pop3.o
OBJECTS         = node.o http.o https.o \
sha256.o base64.o \
db_documents.o db_publishers.o db_crawler.o db_domainindexer.o \
xml_identifier.o xml_documents.o xml_configuration.o xml_publishers.o xml_authentication.o \
main.o

first: all

all: $(OBJECTS)
	$(CC) $(OPTIMIZATION) $(DATABASE_STUFF) $(BOOST_STUFF) $(BOTAN_STUFF) $(OBJECTS) -o $(BUILD_TARGET)

clean:
	rm -rf $(OBJECTS)

clean-all:
	rm -rf $(OBJECTS) $(BUILD_TARGET)

install:
	rm -rf /usr/bin/distributor
	cp $(BUILD_TARGET) /usr/bin/distributor

Here's what I've got so far in my CMakeLists.txt (it's not much, I know):

cmake_minimum_required (VERSION 2.6)

# This is the main CMake build file for Distributor
project (Distributor)

# Add the source directory
add_subdirectory (source)

# Generate an executable from called Distributor from main.cpp
add_executable (build/node.o source/node.cpp)
add_executable (build/Distributor source/main.cpp)

I don't even know if I'm on the right way of adding executables..

I also wonder if I can integrate another CMakeLists.txt (from third party source code (cppdb)) into the project's CMakeLists.txt..
