The NDEBUG macro turns the assert() function into a noop. This gives a |
2 |
small performance boost, but may allow subtle programming errors to go |
3 |
unnoticed. |

This code was added back in 2008, when we started passing |
6 |
-DCMAKE_BUILD_TYPE=None instead of Release or Debug. It probably tries |
7 |
to mimic a default behavior of Release type builds. |

|

Other common build systems do not do this by default. For example, |
10 |
autoconf's AC_HEADER_ASSERT macro only sets NDEBUG if --disable-assert |
11 |
is passed to configure (it defaults to enabled). |
12 |
|
13 |
It is better to let users add this to CPPFLAGS themselves if they really |
14 |
want to save those few CPU cycles. |
