Qt and Web Assembly - Installation, running examples and openCV

[d_stranz]

I don't know if it get used by make, by the compiler or not, or at which state. I usually use cmake but I simply try to understand the basics of it until it works.

This file is used by cmake as it generates the Makefile for Qt WebAssembly.

I think you can define a cmake variable QT_WASM_EXTRA_EXPORTED_METHODS and set it to "specialHTMLTargets" (or append this to what is there if it is already defined, separated by a comma). The script above looks for this variable and appends the contents to the wasm_extra_exported_methods variable, which in turn adds it to the "SHELL: -s" link options.

You might find the QT_WASM... variable defined (but possibly empty) in one of the top-level CMakeLists.txt files for Qt WebAssembly.

Edit: Now that I changed your QUOTE tags to CODE tags, I can see that what you pasted was a function definition. I was misreading it a bit prior to that. Instead of a variable, you may have to look for a call to set_target_properties() or set_property( TARGET ... ) that contains the QT_WASM... name and modify that. See this stackoverflow post about how to use set_property.

My Qt 5.14.2 distribution doesn't seem to have any of the Qt WebAssembly source files, so I can't really check this out.
