+mkdir build
+cd build
+cmake ..

+#This last command is also where you can pass additional CMake configuration flags
+#using `-D<key>=<value>`. Then to build use:
+cmake --build . --config Release
+cd ..

+The optional `test_file_benchmark` arguments are:
+
+- `[loop-count]` = optional loop count. Total number of bytes decoded and formatted is `<code-len> * [loop-count]`
+- `<code-offset>` = offset of the code section (in decimal or 0x hex)
+- `<code-len>` = length of the code section (in decimal or 0x hex)
+- `<filename>` = 64-bit x86 binary file to decode and format
