Pieter, All,

Besides comments by Romain, here are mines:

Are those three dependencies needed for cpprestsdk itself, or are they
inherited from the boost dependencies?

Is the latter, then you need to say so:

    depends on BR2_INSTALL_LIBSTDCPP # boost
    depends on BR2_USE_WCHAR # boost
    depends on BR2_TOOLCHAIN_HAS_THREADS # boost

If not, then that's OK the way you did.

Do you mean that pkgconf is needed on the target at runtime?

I doubt it is. What is needed is only the host variant, no?

Incorrect indentation: it should one leading TAB for all keywords (bool,
depends on, select, help) and a TAB plus two spaces for the help text
itself.

Ditto, indentation.

License and licen files? Again, it does not look like it is easy:

    CPPRESTSDK_LICENSE = Apache 2.0, OpenSSL License, BSD-3c, Boost Software License 1.0
    CPPRESTSDK_LICENSE_FILES = license.txt ThirdPartyNotices.txt

> +CPPRESTSDK_DEPENDENCIES = boost openssl zlib

You also need to depend on host-pkgconf, since it is used to find
websocketpp.

Usually, we try to have the non-conditional options go first, then the
conditional ones:

    CPPRESTSDK_CONF_OPTS = -DBUILD_SAMPLES=OFF

    ifeq ($(BR2_PACKAGE_WEBSOCKETPP),y) 
    CPPRESTSDK_DEPENDENCIES += websocketpp
    else
    CPPRESTSDK_CONF_OPTS += -DCPPREST_EXCLUDE_WEBSOCKETS=ON
    endif
