When compiling a subdirectory, it basically lumps all of the headers and |
| 5 |
source into one big file and sends it to the compiler, which can then use all |
| 6 |
sorts of fancy optimizations since all of the compilation units are in that |
| 7 |
one file, vs. multiple files. It makes compilation a LOT faster and produces |
| 8 |
much more optimized binaries, at the expense of needing much more space for |
| 9 |
temporary files during the compile. Also, it doesn't always get tested 100% |
| 10 |
before a release, so sometimes an #include is missing which causes the |
| 11 |
compilation to fail. |
