reb is a commandline tool designed to work with CMake that embeds resources into C/CPP executables.

Usage

reb takes a file and dumps it's contents into a c-style array, allowing it to be accessed in C/C++ source code.
It takes 3 inputs: output file name (without file type), input resource file and fopen mode

To use this in CMake you can make a custom command:

add_subidrectory(reb)

set(output MyOutputFile)
set(resource /absolute/path/to/MyBinaryOrTextResourceFile.jpg)

add_custom_command(
    OUTPUT ${output}.c
	COMMAND reb ${output} ${resource} "rb"
	DEPENDS ${resource}
)

add_executable(MyExe ${output}.c)

(It is recommened to use rb for binary files and r for text files.)

This will generate a C file called myoutputfile.c with the following definitions:

const unsigned char myoutputfile[] = {
	//File contents as hex
};
const size_t myoutputfileLength = sizeof(myoutputfile);

You can then reference in your executable:

extern const unsigned char myoutputfile[];
extern const size_t myoutputfileLength;
