Trouble compile SQLPage on FreeBSD because of ODBC

[E8y2FqZE]

Introduction

I'm trying to install SQLPage on FreeBSD in a managed hosting environment where I cannot install system packages. FreeBSD binaries are not provided here on GitHub, so I need to compile it myself. Cargo is available and an old version of SQLPage compiled just fine. Now, I'm getting errors with the latest version. I'm only using SQLite, so if there's a flag to disable ODBC entirely, that would be beneficial.

To Reproduce

RUSTFLAGS="-C codegen-units=1" cargo install sqlpage --version 0.42.0

Successfully compiles all packages except sqlpage and then produces the following error at the end when linking:

error: linking with `cc` failed: exit status: 1
  |
  = note:  "cc" "-m64" "/home/tmp/rustclB7aYi/symbols.o" "<2 object files omitted>" "-Wl,--as-needed" "-Wl,-Bstatic" "/home/tmp/cargo-installjJbC1y/release/deps/{libenv_lo...

(... snip ...)
  = note: ld: error: unable to find library -lodbc
          cc: error: linker command failed with exit code 1 (use -v to see invocation)
          

error: could not compile `sqlpage` (bin "sqlpage") due to 1 previous error

I'm not allowed to modify this environment and install libodbc because it's a managed/shared web hosting environment. So I tried compiling with the --features odbc-static flag:

RUSTFLAGS="-C codegen-units=1" cargo install sqlpage --version 0.42.0 --features odbc-static

Which produced this error:

Any ideas on how to disable ODBC entirely or appease the compiler here?
