[mlpack-git] [mlpack/mlpack] Default to DEBUG=OFF and PROFILE=OFF. (#662)

[Yannis Mentekidis]

Most people (myself included) will closely follow directions in the README before trying alternative install configurations, meaning if we make it slightly easier for them to just copy-paste commands on the terminal they will stop compiling with debug symbols.

For example, now README.md describes the installation process like this:

> The next step is to run CMake to configure the project [...]
> `$ cmake ../ `
>You can specify options to compile with debugging information and profiling information:
>`$ cmake -D DEBUG=ON -D PROFILE=ON ../`

We could have it say instead:

> The next step is to run CMake to configure the project [...]
>  `$ cmake -D DEBUG=OFF -D PROFILE=OFF ../ `
> 
> You can specify options to compile with debugging information and profiling information:
>  `$ cmake -D DEBUG=ON -D PROFILE=ON ../`
> Be warned, this will make mlpack significantly slower and is intended for mlpack developers

 

(Or something like that)
