* [build][cmake] set lib m as public so it can be linked by consumer

* [build][cmake] removed redundancy when BSD systems

* fix web build issue with CMake introduced by #5181

* remove ASYNCIFY

It is recommended to use lowercase CMake commands

// File management functions
 - int FileRename(const char *fileName, const char *fileRename); // Rename file (if exists)
 - iint FileRemove(const char *fileName);                         // Remove file (if exists)
 - iint FileCopy(const char *srcPath, const char *dstPath);       // Copy file from one path to another, dstPath created if it doesn't exist
 - iint FileMove(const char *srcPath, const char *dstPath);       // Move file from one directory to another, dstPath created if it doesn't exist
 - int FileTextReplace(const char *fileName, const char *search, const char *replacement); // Replace text in an existing file
 - iint FileTextFindIndex(const char *fileName, const char *search); // Find text in existing file

// Text management functions
 - const char *TextRemoveSpaces(const char *text);                                       // Remove text spaces, concat words
 - char *GetTextBetween(const char *text, const char *begin, const char *end);           // Get text between two strings
 - char *TextReplace(const char *text, const char *search, const char *replacement);     // Replace text string (WARNING: memory must be freed!)
 - char *TextReplaceBetween(const char *text, const char *begin, const char *end, const char *replacement); // Replace text between two specific strings (WARNING: memory must be freed!)

For some reason, #5181 deleted it.
This project is intended to be a simple template to set up a project
consuming raylib with CMake.

Currently, scaling doesn't work correctly on macOS (see #5185).  This commit
works around this issue by disabling SCALE_FRAMEBUFFER on macOS when
`FLAG_WINDOW_HIGHDPI` is unset.

* [cmake] export automatically raylib definitions and compile/link options

* [cmake] pass emscripten options to consumer project

* [web] compile for web

* [web] canvas width 100%
